To @ZZ whom it may concern.-

Be it known that I, DAVID L. TEEXLEE, of Lexington, in the county ofDavidson and State of North Carolina, have invented certain new anduseful Improvementsy in Chair- Braces; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon,which form a part of thisspecification.y

This invention relates to certain improvements in braces and tightenersfor chairs, and the like.

The object of the invention is to provide an improved brace exceedinglycheap, simple and durable in construction and composed of a minimumnumber of parts.

The invention consists in certain novel features of construction and incombinations of parts more fully hereinafter described and particularlypointed out in the claim.

Referring to the accompanying drawings:- Figure l is a perspective viewof my present invention applied to a chair. Fig. 2 is a longitudinalsectional view through the tightener of the brace. Fig. 3, is atransverse section-through the tightening device showing the bracewires, the section being taken on the lines oc-a; Fig. 2.

In the drawings the reference letter a, in# dicates a chair providedwith the vusual leg's b. Each chair leg is provided with suitable hooksor eyes o, secured thereto near the upper and lower ends thereof. Thetwo brace wires d, extend between the legs and are at their endsconfined to the lower hooks c of the opposite legs. The two brace wiresd are correspondingly arranged and connected to the upper hooks c, ofthe legs.

e, indicates a brace wiie or connection at its ends secured to oppositesides of the seat of the chair and depending therefrom. These wires areall connected and tightened by the tightening device e.

f, indicates the movable tightening head of the tightening deviceprovided with a screw threaded shank gextending downwardly and withtransverse holes 7i., extending through the head a distance below itsupper end as shown. The brace wires extend through these holes of thehead, the wires being preferably strung through the holes beforethey aresecured at their ends. If desired vertical grooves fi, can be formedlongitudinally in the head from said holes to the upper edge of the headto receive the wires and prevent injury thereto. The head j is hereshown provided with separate transverse openings h, h, arranged indiiferent vertical planes for the two sets of wires d, d', respectively,and with a separate aperture 71.', for the depending brace or supportwire e. This head is located in the socket j having the approximatelycylindrical interior and the threaded shank of the tightener passes downthrough the bot-tom of the socket and is provided with a nut k, or otherscrew threaded means for drawing the head downwardly within the socket,so that the wires connected thereto will be tightly stretched by beingdrawn down into the socket over the upper edge of theY socket which isslightly rounded for this purpose. The brace attached to the seat of thechair draws the tightener up close to the bottom of the seat and alsofirmly holds the legs to the seat while the-cross braces d and d', drawthe legs toward each other and hold them firmly in position.

The operation of this device will be easily understood, and itssimplicity appreciated.

The wire connections can be maintained exceedingly tight by simplyturning the screw threaded nut or thumb screw, or the braces can beloosened if desired. The construction is exceedingly simple andinexpensive and very durable.

v The device can be used with bedsteads or other like articles by merelyrunning the braces to the opposite corners, sides, or ends of the bed orframe.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

The tightener composed of the open socket having the rounded edge, thehead movable longitudinally in the socket and provided with transverseopenings and vertical guide Ways extending up from said openings, means,my own I affix my signature in presence of two substantiallly asdescribed to move sid head longitudine ly in t e socket, and t e bracewires passing through said head and up said DAVID L' TREXLER' Witnesses:
